I've found a pretty good jQuery Validation plugin, it includes
different languages (in the localization folder), however
I haven't found a way to actually use them, how do I make it use German for instance?
I only needed to add the localization files after the validation plugin.
<script type="text/javascript" src="jquery.validate.js"> </script>
<script type="text/javascript" src="localization/de.messages.js"> </script>
